.is a partially-sectional elevation of the mainwire feed, looking in the direction of arrow l, Fig. 1; and'Fig.'8is aside elevation of the cam and levers for operating the barb-wire feed. Fig. 91s aperspective view of the head, 'and Fig. 10 a perspective view of'the' block, both enlarged, and hereinafter fully de scribed; v 1 1 The object'ofthis machine is the rapid manufacture of barbedwires for fencing, taking the main" wires from the reel, feeding them through a hollow shaft, and -taking the barbwires'from reels,*feeding them tothe main bearings; The bearings .for the upper shaft wires, cuttin g therefrom th'e-barb blanks, and

twistin g them onto and around the main wires atsuitable intervals, said machine being con structed and operating substantially as hereinafter described and claimed. i

In the drawings, A is a bed-pl'ate, su orted by suitable legs, and upon which are arranged all the working' parts of y the machine. B is a hollowshaft, set in hearings on the blocks B B, and has a pinion, B. Beneath said shaft B is a segment-gear, C, also having its bearings iirthe lower part of said blocks B. Dis a pitman attached to the segment-gear, pro vided at its opposite end with a slotted frame, D, in which a cam, D, plays, and by means of whichmotion is imparted to the said seg-.

ment-gearL The cam D" is fixed' on a shaft, E, having its hearings in the .three blocks E" E E. This shaft E has a gear-wheel, F, connected with a pinion,'F, on a parallel shaft, G, which also has a gear-wheel, G, putside of.

the block E, at the end-of'the'machine. 'This gear G connects with a pinion, G, on a short shaft, G, and upon which are the drivingpulleys, from which the whole machine'derives its motion.

having a face sli htly cone-shaped, an provided with two cutters, h It, one, located on each side, of the 'opening through which the main wirepasses These cutters.ai e in slots inthe sides of the head,'and are held in place by plates h h, bolted to the saidhead.

This is for the convenience of removing for sharpening,;&c. Opposedtothe head H isa block, I, pivoted between two'posts, I I. A This blockhas a reciprocatory movement imparted to it by a pitma'n, 1', connected therewith, and

operated by a double cam, 2", playing in a slotted frame onits opposite end. Said cam is fixed on a counter-shaft, J, having its bearings in'the b'oXes-J J J on the bed-plate AL" This shaft J derives its motion through a bevel-gear,-j,-'connected with a bevelrpinion, j,.on .a shaft, K, driven bya pinion k, con-'- necting it withthegear Fon'the shai t .Ini.'-conriection'withfthe hollow shaft 'Bis "a ,feed mechanism, consisting of a pair. "of feed 1 wheels, L Ii,- whose shafts have their hearings in the blocks L L. Said shafts are geared to run together by gears I? L outside of the are set in' adjustable boxes, which are regulated byset-screws for regulating the tension ofsaidlwheels upon the wire. The lower shaft is provided with a loose pinion,'m, having a dog, jm, which plays in a ratchet on the said -shaft. By the side of said ratchetand pin ion is arranged a rack, .n, (see Fig. 7,)1playing in slides a, attached to the side of one of the" blocks L. This rack meshes with theafores'aid loose pinion m, and is operatedby a con;

necting-rod,-o', connecting it with a'rocking' lever, 0, pivoted in apost, O. The other'end of said lever O is connected with a pitman,'P,

having a slotted frame on its lower end, in,

which a cam, P, on shaft E plays, and from To the hollow sliaft B is fixed a headlfl, 1s

i ihr movements. 1

In connection with the revolving cutter and twisting-head H is also a feedi'nechanism for feeding the barb-wiresto the said head, con sisting of'two setsof feedwheels, Q Q Q Q, one pair located on each side of the head H. The

e'ed jrmechanism derlves itsbearings for the shafts of the said feed-wheels are fixed in frames- ,1? :Rt'lirlh, secured towthe posts and blocks at both sides of the head H," the bearings consisting of adjustable boxes,

regulated by setserews for regulating the ten-. $1011.; Each pair of shafts of the said feedwheels are geared to run together with gears S S S S,'and are provided with ratchet-wheels anddogs 3's, the said dogs being attached to;

' loose cranks t t, and said cranks being connectcdby aconnecting-rod, a, by. means of which the two pairs of feed-wheelsywork in concert :lhis feed mechanism derives its movements by meansof a pitman, r, connecting one of the said cranks .t' with arocking lever,- W, pivoted at the opposite end in .the'

top of a post, W and operated by ,a pitman, V having a slotted-frame on its lower end, and operatediby afca n, "W, on the countershaftJ. (See Fig.8.)

Onthe top of thertw o posts I I are fixed,

-with one endin; the .slot ;in,theface of the head H and'the other end-in the slot in the face of the block I, so that when the head re-'- volves it" will windt-he blank around the main The operation of this machine is as follows The main wire is fedthrough the hollow shaft by the feed mechanism at thecndof said-shaft by-intermittent movementscausedby the cam P onshaft 16.. Then the barb-wiresare fed by thc'fecd mechanism at theo positc end of. saidhollow shaft. When this isdone, during the intervalsof movements. of. the aforesaid feed mechanisms, thehollow shaft makes its revolutions, and .thc -barbs. are. cut off and wound aroundsaid main" wires by the move--: mentsof said shat-tit. This cutting off of the barbs will more, plainly appear by reference-to: Fig. 2, whcrethe wires, of whichuthcreare two to make a four-point barb, are'shown in position upon the-face of the head- .lli One wire is beneath the edge of one of -thc-knive s hxiand the ot-heris just above the edge of :the opposite knife. The cutting-edges; of. these knives are thcirin line with thosc of the-stationary knives h It, so that'wheii the hea'dis rotated the "knives act =to I cut oif the barbs'x At this time the block I is held in close conhead H.

tact withthe head H, with 'thebarb-blanks be+ tween them, the said-blanks being heldin the slots in the face of the blockl at one end, and

.their other ends resting in the slots in the The rotating head H carries its ends of the barbs about the main wire, interlocks them, and secures the barbs by about a threefourths turn to the main' wire.

- As soon as the shaft B has performed its revolution for twisting the barbs the block I recedes from the head H by means of the cams ion the eounter'vshaft J. At the same time the shaft 13 is revolved back again through the medium of the segment-gear G, operated by the pitman-D and the cam I)" on the shaft E.

One of the cams has a complete half-circle, forthe purpose ofretaining the block I in place up, against the head during its revolu t1on of twisting the barb. The cams are so, arranged on their shafts and in their relation to each other as to operate and perform the several movements of different parts of the machine at the successive intervals stated and I for producing the results described.

p The machine is automatic, for it takes the; main wires from the reels,'passes them through the hollow shaft and head, takes, the barbwiresalso from the, reels, feeds them to the revolving cutting and twisting head, cuts off the barb-blanks, twists. them onto the main wires, and passes the finished barbed wire I to the spools, where it is wound, ready for useor.

. I do not claim in this application the combination of the head H and block I. Nor do I herein broadlyclaini the combination. of maul-i anismconstructed and arranged to automati: cally feed forward the fence ormain wire at stated intervals, with mechanism to secure the barb about the fence-wire, andmechanism to ,feed forward the barb-wires at stated intervals across the fence-wire, and mechanism for cut-- ting off the barb-wires; but I reserve to my-.

self the rightand intend to embody such com binations in future applications.

In Figs. 9 and 10 the. details of the construction of the head 1i and block I. are more fully represented. Groovesor slots land 2 are madcpartly across thefaceof the head to, receive the barbwvires, and a cavity or recess,

3, is made between these groovesor slots, and

surrounds the opening continuous of the bol low shaft-or spindle, in: which cavity the protuberance upon the mainwire resulting from thexwinding of the barbs upon. it is received,

one half of such protuberance lying within said cavity3 and the other port-ion within a- --cavity, 6, in the block I. This block is .pro- .vided with slotslor grooves 4 and 5,-that reglistcnwith:thegroovcs or slots -1 and 2.0f the head H, to. hold the barbs while they are being secured to thel'ence-wire, as hcreinbefore described-q;
